Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive repair tools, specifically to a yoke splitter. Background Technology
[0002] In automotive repair and maintenance, operations such as four-wheel alignment, suspension system overhaul, shock absorber replacement, and steering knuckle (commonly known as "steering knuckle") removal and installation often require separating the steering knuckle from its connected components (such as the control arm ball joint, shock absorber strut, and steering tie rod end). These connections typically employ a tapered fit structure (i.e., tapered surface + self-locking nut), relying on preload to achieve a tight connection. However, after prolonged use, these connections are prone to becoming difficult to disassemble due to rust, oil stains, or mechanical seizing. Traditional disassembly methods mostly rely on hammering, prying with a crowbar, or using general-purpose pullers. These methods are not only inefficient but also easily damage the tapered surface or dust cover of the ball joint pin, leading to seal failure and affecting subsequent assembly accuracy. Furthermore, they are unsuitable for modern compact chassis structures with limited space, as their large size makes operation difficult within the narrow wheel arches. This is especially true for highly integrated and compact new energy vehicle or high-end passenger vehicle chassis, where traditional separation tools often cannot effectively intervene, making disassembly extremely inconvenient. Summary of the Invention
[0003] The purpose of this invention is to provide a horn separator to solve the problem that the tools used in the traditional disassembly methods mentioned in the background art are large in size and easily damage the parts.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a horn separator, comprising a cylinder, wherein a limiting block is inserted and installed on the outer surface of the cylinder, and a screw is fixedly provided on the outer surface of one end of the limiting block; a bottom block is fixedly installed on the outer surface of one end of the cylinder, and a nut is rotatably installed inside the bottom block, and a threaded barrel is fixedly installed on one side of the nut; the threaded barrel is located inside the cylinder, and the inner surface of the cylinder is in contact with the outer surface of the threaded barrel; the screw and the threaded barrel are concentrically designed, and the threaded barrel and the screw are threadedly connected.
[0005] Preferably, the bottom block is fan-shaped, and the width of one end of the bottom block is greater than the width of the other end. The limiting block is L-shaped, and the outer surfaces of both sides of the limiting block are in contact with the outer surface of the cylinder. One end of the limiting block is located on the outside of the cylinder. The outer surface of the limiting block is in contact with the outer surface of the bottom block, and one end of the limiting block is level with one end of the bottom block. The end of the limiting block located on the outside of the cylinder is inclined.
[0006] By adopting the above technical solution, the design of the extended bottom block and the limiting block, along with the inclined design of the limiting block, ensures that the limiting block will not easily detach after moving inside the cylinder. Combined with the clamping at one end of the bottom block, it makes disassembling parts more convenient and less likely to cause them to detach and fly away, thus avoiding danger.
[0007] Preferably, a screw is threaded onto one side of the outer surface of the cylinder, and clamping and limiting grooves are provided on both sides of the cylinder, with the clamping and limiting grooves being designed in parallel. An insertion limiting mechanism is provided between the screw and the threaded cylinder.
[0008] By adopting the above technical solution, the top block can be moved effectively by tightening the screws, so that the fixed threaded barrel can be confined inside the cylinder.
[0009] Preferably, the insertion limiting mechanism includes: a sliding groove, the sliding groove being opened inside one side of the cylinder, a top block being slidably installed inside the sliding groove, and the top block being arc-shaped, the top block being rotatably connected to the screw, a groove being opened on the outer surface of the threaded barrel, and the groove of the threaded barrel being inserted into the top block, and the top block being in contact with the outer surface of the threaded barrel.
[0010] By adopting the above technical solution, the rotation of the screw can drive the top block to move flexibly inside the slide groove. When the threaded barrel needs to be inspected or replaced, it can be removed from the cylinder for inspection and maintenance. The top block can be pushed out and locked into the slide groove and the threaded barrel to limit the position of the threaded barrel. This allows for easy control of the extraction and fixing of the threaded barrel when it needs to be replaced or inspected, and ensures that the threaded barrel can rotate smoothly.
[0011] Preferably, an upper ring is engaged with one end of the threaded barrel near the nut, and a lower ring is engaged with the inside of the barrel, wherein the lower ring does not fit against the outer surface of the threaded barrel. The upper ring and the threaded barrel are interference fit, and the lower ring and the barrel are interference fit. A ball bearing is provided between the upper ring and the lower ring, and the ball bearing has rolling friction with the upper ring and the lower ring.
[0012] By employing the above technical solution, the use of the upper ring, rolling balls, and lower ring can effectively drive the movement of the nut rotation, thereby moving the limiting block and screw. When the bottom block and limiting block move and push to separate automotive parts, the nut can rotate more smoothly and easily. The rolling balls can also effectively distribute the compressive force of the nut evenly, allowing the nut to rotate easily without crushing it. This greatly extends the service life of the upper ring, rolling balls, and lower ring. Furthermore, the upper ring, rolling balls, and lower ring can be removed and replaced by disassembling the threaded barrel, further extending the service life of the nut separator.
[0013] Preferably, the inner side of the cylinder near the lower ring has a spacer groove, and the spacer groove does not fit with the outer surface of the lower ring. The lower ring, the upper ring and the cylinder are concentrically designed.
[0014] By using the above technical solution, the lower ring can be easily knocked out and removed from the cylinder through the use of the spacer groove, which greatly reduces the difficulty of disassembling the cylinder after the lower ring is damaged.
[0015] Preferably, the side of the cylinder away from the screw has a contact surface, and the contact surface is designed to be perpendicular to the bottom block.
[0016] By adopting the above technical solution, the bonding surface on one side of the cylinder can be effectively bonded to the automotive parts through the set bonding surface, and the bottom block and limit block will not be unable to be stably fixed due to the curvature of the cylinder.
[0017] Compared with the prior art, the beneficial effects of the present invention are: the horn separator: 1. By splicing and inserting the cylinder and the limiting block, and connecting it with the screw and the threaded barrel, the limiting block can move up and down inside the cylinder while being limited by the cylinder. This allows the bottom block and one end of the limiting block to move away from each other and push the parts apart after being inserted, thus reducing the overall size of the horn separator. This allows the horn separator to be used easily in confined spaces without obstruction and reduces the chance of damage to automotive parts due to impact. 2. By using the upper ring, rolling ball, and lower ring, the bottom block and the limiting block can be moved and staggered and subjected to force, which can also reduce the friction generated when the nut and the cylinder rotate, improve the smoothness of disassembling car parts, and reduce the force required to rotate and separate car parts when the tool is inserted into the clamping limiting groove and the nut is rotated, greatly improving the convenience of use. 3. The top block can be moved inside the slide groove by rotating the screw. When the top block moves inside the slide groove, the engagement state between the top block and the threaded barrel can be flexibly switched. This allows the threaded barrel to be easily fixed and removed from the inside of the cylinder. It also makes it convenient to replace the upper ring, rolling ball, lower ring and other parts through the interval groove, which greatly improves the convenience of inspection and maintenance of the horn separator.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-6 The present invention provides a technical solution: a horn separator, comprising a cylinder 1, a limiting block 3 inserted and installed on the outer surface of the cylinder 1, and a screw 4 fixedly installed on the outer surface of one end of the limiting block 3; a bottom block 2 fixedly installed on the outer surface of one end of the cylinder 1; a nut 5 rotatably installed inside the bottom block 2; and a threaded barrel 7 fixedly installed on one side of the nut 5. The threaded barrel 7 is located inside the cylinder 1, and the inner surface of the cylinder 1 is in contact with the outer surface of the threaded barrel 7. The screw 4 and the threaded barrel 7 are concentrically designed, and the threaded barrel 7 and the screw 4 are threadedly connected. The bottom block 2 is fan-shaped, and the width of one end of the bottom block 2 is greater than the width of the other end. The limiting block 3 is L-shaped, and the outer surfaces of both sides of the limiting block 3 are in contact with the outer surface of the cylinder 1. One end of the limiting block 3 is located on the outside of the cylinder 1. The outer surface of the limiting block 3 is in contact with the outer surface of the bottom block 2, and one end of the limiting block 3 is flush with one end of the bottom block 2. The end of the limiting block 3 located on the outside of the cylinder 1 is inclined. A screw 8 is threaded on one side of the outer surface of the cylinder 1. Clamping and limiting grooves 6 are opened on both sides of the cylinder 1, and the clamping and limiting grooves 6 are parallel. A contact surface 15 is opened on the side of the cylinder 1 away from the screw 8, and the contact surface 15 is perpendicular to the bottom block 2.
[0022] Firstly, when using it, simply insert the bottom block 2 and the limiting block 3 into the parts of the car chassis, and make the contact surface 15 contact the outer surface of the car parts. Then, insert a tool into the clamping limiting groove 6 and use the tool to turn the nut 5. The nut 5 will drive the threaded barrel 7 to rotate, allowing the threaded barrel 7 to drive the screw 4 to move. This allows the limiting block 3 to move and rise inside the cylinder 1. Utilizing the inclined design of the limiting block 3, after the limiting block 3 and the bottom block 2 move and open, they can be firmly locked between the car parts. As the limiting block 3 moves, the car parts can be easily separated for disassembly, greatly reducing the overall size and area of the clutch separator, making it convenient for use in confined spaces.
[0023] An insertion limiting mechanism is provided between the screw 8 and the threaded barrel 7. The insertion limiting mechanism includes a slide groove 10, which is opened inside one side of the barrel 1. A top block 9 is slidably installed inside the slide groove 10. The top block 9 has an arc design and is rotatably connected to the screw 8. A groove is opened on the outer surface of the threaded barrel 7, and the groove of the threaded barrel 7 is inserted into the top block 9. The top block 9 is in contact with the outer surface of the threaded barrel 7.
[0024] Secondly, during maintenance, loosening screw 8 will retract the top block 9 into the slide groove 10, disengaging it from the threaded barrel 7 and allowing it to be removed from the cylinder 1. The limiting block 3 and screw 4 can then be removed by rotating nut 5, facilitating the replacement and maintenance of parts such as the threaded barrel 7, top block 9, limiting block 3, and screw 4 after prolonged use. Furthermore, the lower ring 13 can be easily removed through the spacer groove 14, significantly improving the convenience and lifespan of the horn separator during maintenance. The threaded barrel 7 is fitted with an upper ring 11 near the nut 5. The lower ring 13 is fitted inside the cylinder 1, and the lower ring 13 does not fit against the outer surface of the threaded barrel 7. The upper ring 11 and the threaded barrel 7 are interference fit, and the lower ring 13 and the cylinder 1 are interference fit. A ball bearing 12 is provided between the upper ring 11 and the lower ring 13, and the ball bearing 12 has rolling friction with the upper ring 11 and the lower ring 13. A spacer groove 14 is provided inside the cylinder 1 on the side near the lower ring 13, and the spacer groove 14 does not fit against the outer surface of the lower ring 13. The lower ring 13, the upper ring 11 and the cylinder 1 are concentrically designed.
[0025] Furthermore, the use of the upper ring 11, the rolling ball 12, and the lower ring 13 can effectively distribute the friction force when the nut 5 is separating car parts. The quenching of the upper ring 11 and the lower ring 13, and the stainless steel material of the rolling ball 12, make the nut 5 more convenient and less strenuous when rotating and under force. The upper ring 11, the rolling ball 12, and the lower ring 13 are also more wear-resistant and robust, making it more convenient and less strenuous to separate car parts without causing difficulty in rotation due to friction.
[0026] Working principle: When in use, simply insert the bottom block 2 and the limiting block 3 between the car parts, and make the contact surface 15 fit against the outer surface of the car parts. Then, insert a tool between the clamping and limiting grooves 6 to fix the cylinder 1. Then, rotate the nut 5 and drive the threaded barrel 7 to rotate together, so that the threaded barrel 7 can drive the screw 4 to rotate, so that the limiting block 3 can move along the direction of the cylinder 1, so that the bottom block 2 and the limiting block 3 can separate from each other and squeeze the two parts of the car to separate the steering knuckles of the car.
[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
